TOKYO, Sept 18 (Reuters) - Japanese government bonds edged up on Friday and were on track to end the week higher, with yields at their lowest levels since early August on robust demand after major central banks signalled sustained easy policy ahead.
Demand for medium-term maturities was strong this week, coming from both domestic and international investors, said a trader at a Japanese brokerage.
The bullish mood came as central banks in the United States, Japan and Britain all suggest this week they are committed to extremely easy monetary policy.
The five-year yield fell 0.5 basis point to minus 0.120%, its lowest level since Aug. 5.
The 10-year JGB yield stood at 0.010%, flat from previous close, which was also the lowest level since early last month.
Benchmark 10-year JGB futures rose 0.04 point to 152.09.
Trade was tepid ahead of a long weekend in Japan. The market will be closed on Monday and Tuesday for public holidays.
The 20-year JGB yield was flat at 0.390% while the 30-year yield was also unchanged at 0.585%.
